    I've only just noticed that the 112 can be used in SKA timetable, I guess it replaced the 143. As much of the route is LZB I got excited to be using it.

    However, there's no target speed displayed or red V Sol needle bug. Is this a bug, or am missing something. If so, can the loco be used using PZB only as you can't drive under LZB as the system isn't telling you what speed to be doing. All I see is the km display counting down to the next restriction.

    I noticed this too. In the 112 I dont even recognise the display for the LZB speed, so not even sure it was fully integrated.

    As the loco can only go up to 160km/h, you can drive it using PZB only, though. As long as LZB is not active, PZB will take over. As the rest of the LZB system is not very close to reality, I tend to use it as little as possible any way (v >160km/h), at least for the moment.

    I don't think this older LZB system shows the subsequent speed. In addition, you continue to control the train manually. If control indicator G illuminates, this means that you are approaching the braking point. Start braking until control indicator G goes out. This will reach the maximum permitted speed in the following section. If control indicator G flashes, this means that you have exceeded the braking point by 5 km / h. The DBBR 112 locomotive is excellent for this line.

    No, LZB always consists of three V indicators, Vsoll (Vshall), Vist (Vis) and Vziel (Vtarget). If you only have the breaking point indication, you would be completely in the dark to what speed you have to break to. This is not how it works.

    You are, however, absolutely right about the manual control, as there is no AFB linked to the LZB, you are doing it manual, with the guidance of the indications in front of you.

    Following schematic is taken from RIL 483.0202 (I think your picture comes from the same document?!), which explains the principal of LZB:

    In the TSW2 BR112 you are missing Vziel and Vsoll.

    Also, the next image comes from RIL 493.0143, the official handbook of the 143/112, showing the Vziel indication as well:

    Just in case someone is interested in the operation of the LZB with all its special cases and in its full complexity, here is the Link to RIL 483.0202

    I was thinking of maybe picking up HHL on a sale someday, but if bugs like that continue I'll be waiting on that I think.

    For HHL it does not have any impact, as you dont have LZB on that line. Its purely a bug if you put the loco on an LZB equipped route. On HHL the 112 works quite nicely:)

    Yeah, but if it replaces the 143 on SKA that does become an issue for me, as I quite like playing all the different services on SKA and would also like to play the RE services with LZB on that route. Still not sure what I'll do with HHL, I'll just wait until the next sale and then ask some people what it's like and think about whether I'll buy it.

    Yes vSoll and vZiel are missing off the TSW version, so it's not really possible to know when advance signals change state. They exist in the TS1 vR version of the 112. As OpenMinded said though you can just run with PZB on SKA by switching it on in the motor room corridor. I just wondered whether DTG were aware LZB on the 112 was incorrectly modelled and pretty much unusable in its present state.
